## Introduction

Atomic Agent is an open-source AI agent that runs on your machine and supports local models through llama.cpp. Connect it to 1,500+ apps through Composio, including Kickbox.
This guide uses Atomic Agent's built-in Composio integration. You need Atomic Agent v0.5.6 or later, your own Composio API key, and a Kickbox account. See the [Atomic Agent documentation](https://atomicagent.io/docs/?cta_placement=atomic-agent-docs) for installation instructions.

## TL;DR

### How Atomic Agent connects to Kickbox
Atomic Agent connects to Composio's Tool Router over Streamable HTTP MCP. It discovers the tools needed for your request, and Composio handles account authentication.
Execution and account-connection tools follow Atomic Agent's configured approval policy. Review any approval prompt before allowing an action on your connected account.

## Connect Kickbox to Atomic Agent

### Connect Kickbox to Atomic Agent
- Sign up or sign in to the [Composio dashboard](https://dashboard.composio.dev/?cta_placement=atomic-agent-api-key). Copy your API key.
- In Atomic Agent, open the Integrations tab and select Composio. Select API key, press e, paste the key, and press Enter. The tools become available immediately, without a restart.
- Ask Atomic Agent to do something in Kickbox. It searches Composio for the right tool.
- On first use, open the sign-in link returned in the chat. Connect your Kickbox account, then return to Atomic Agent to continue.
### Headless setup
Add the following line to ~/.atomic-agent/.env, replacing YOUR_COMPOSIO_API_KEY with your key. Start Atomic Agent after saving the file.

```bash
COMPOSIO_API_KEY=YOUR_COMPOSIO_API_KEY
```

## What is the Kickbox MCP server, and what's possible with it?

The Kickbox MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Kickbox account. It provides structured and secure access to real-time email verification and quality scoring, so your agent can instantly validate email addresses, reduce bounce rates, and maintain clean contact lists on your behalf.
- Instant single email verification: Ask your agent to check if an email address is valid and deliverable before sending important communications.
- Preventing invalid email submissions: Ensure only legitimate and active emails are accepted into your systems, reducing bounce risk and protecting sender reputation.
- Real-time workflow integration: Validate emails as part of onboarding, registration, or transactional processes to catch errors and typos immediately.
- Email quality scoring: Assess the likelihood of deliverability and filter out risky or low-quality addresses from your lists.
- Automated contact list hygiene: Regularly verify individual emails to keep your CRM and marketing lists accurate and up to date.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `KICKBOX_CHECK_DISPOSABLE` | Check Disposable Email | Tool to check if an email address or domain is from a disposable email service. Use when you need to validate whether an email is temporary or throwaway (e.g., mailinator.com, trashmail.com). This is a free public endpoint that does not require authentication. |
| `KICKBOX_KICKBOX_SINGLE_VERIFICATION_API` | Kickbox Single Verification | Tool to verify a single email address via Kickbox. Use when you need real-time validation of an individual email before critical workflows. |

## Supported Triggers

None listed.

## Troubleshooting

### Why is my API key rejected?

Copy the key directly from the Composio dashboard. Atomic Agent requires ASCII characters because it sends the key in an HTTP header. Remove any extra characters introduced when copying.

### Why are Composio tools unavailable after saving a key?

Check that you use Atomic Agent v0.5.6 or later and that Composio is enabled in your configuration. A "composio": { "enabled": false } setting disables the integration while keeping the saved key on disk.

### Does Composio have a free plan?

The Hobby plan includes 100,000 tool calls per month. Composio-managed OAuth apps have a lower included allowance. See [Composio pricing](/pricing) for the current limits that apply to your connection.

## Complete Code

None listed.

## Conclusion

### Use Kickbox from Atomic Agent
With your account connected, ask Atomic Agent to work with Kickbox in natural language. You can connect more apps through the same Composio integration as you need them.

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Kickbox MCP?

With a standalone Kickbox MCP server, the agents and LLMs can only access a fixed set of Kickbox tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Kickbox and many other apps based on the task at hand, all through a single MCP endpoint.

### Can I use Tool Router MCP with Atomic Agent?

Yes, you can. Atomic Agent fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Kickbox tools.

### Can I manage the permissions and scopes for Kickbox while using Tool Router?

Yes, absolutely. You can configure which Kickbox scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

### How safe is my data with Composio Tool Router?

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Kickbox data and credentials are handled as safely as possible.
